大分子运动数据库（http://MolMovDB.org）是与蛋白质和RNA结构的灵活性有关的数据和软件的集合。该数据库分为两部分。首先，代表分子不同状态的已解决结构的变形集合提供了灵活性的定量数据和许多图形表示。其次，根据构象变化类型（例如铰链域或变构）对已知运动进行分类，结合了文本注释和来自与运动相关的文献的信息，将许多变形链接在一起。正在开发各种变形子集用于统计分析。特别是，对于每个子集，可以导出各种运动量（例如最大旋转）的分布，这些运动量可用于将特定运动置于上下文中，作为给定群体的典型或非典型运动。在过去的一年里，数据库得到了极大的扩展和增强，纳入了新的结构并提高了数据质量。形态服务器使数据库用户能够从自己的研究或 PDB 中添加新的形态，该服务器也得到了增强，可以处理核酸结构和多链复合物。
The Database of Macromolecular Movements ( http: / / MolMovDB. org) is a collection of data and software pertaining to flexibility in protein and RNA structures. The database is organized into two parts. Firstly, a collection of morphs of solved structures representing different states of a molecule provides quantitative data for flexibility and a number of graphical representations. Secondly, a classification of known motions according to type of conformational change ( e. g. hinged domain or allosteric) incorporates textual annotation and information from the literature relating to the motion, linking together many of the morphs. A variety of subsets of the morphs are being developed for use in statistical analyses. In particular, for each subset it is possible to derive distributions of various motional quantities ( e. g. maximum rotation) that can be used to place a specific motion in context as being typical or atypical for a given population. Over the past year, the database has been greatly expanded and enhanced to incorporate new structures and to improve the quality of data. The morph server, which enables users of the database to add new morphs either from their own research or the PDB, has also been enhance to handle nucleic acid structures and multi- chain complexes.
